INDOOR LOCALIZATION USING ANALOG OFF-AIR ACCESS UNITS

摘要

A system for indoor localization using GPS signals in a Distributed Antenna System includes a plurality of Off-Air Access Units (OAAUs). Each of the plurality of OAAUs is operable to receive a GPS signal from at least one of a plurality of GPS satellites and operable to route signals optically to one or more HUBs. The system also includes a plurality of remote units (RUs) located at a Remote location. The plurality of RUs are operable to receive signals from a plurality of local HUBs. The system further includes an algorithm to delay each individual GPS satellite signal to provide indoor localization at each of the plurality of RUs.
